Simplifying -2x2 + 2x + 5 = -1x2 + -1x + -1(1 + -1x2) Reorder the terms: 5 + 2x + -2x2 = -1x2 + -1x + -1(1 + -1x2) 5 + 2x + -2x2 = -1x2 + -1x + (1 * -1 + -1x2 * -1) 5 + 2x + -2x2 = -1x2 + -1x + (-1 + 1x2) Reorder the terms: 5 + 2x + -2x2 = -1 + -1x + -1x2 + 1x2 Combine like terms: -1x2 + 1x2 = 0 5 + 2x + -2x2 = -1 + -1x + 0 5 + 2x + -2x2 = -1 + -1x Solving 5 + 2x + -2x2 = -1 + -1x Solving for variable 'x'. Reorder the terms: 5 + 1 + 2x + x + -2x2 = -1 + -1x + 1 + x Combine like terms: 5 + 1 = 6 6 + 2x + x + -2x2 = -1 + -1x + 1 + x Combine like terms: 2x + x = 3x 6 + 3x + -2x2 = -1 + -1x + 1 + x Reorder the terms: 6 + 3x + -2x2 = -1 + 1 + -1x + x Combine like terms: -1 + 1 = 0 6 + 3x + -2x2 = 0 + -1x + x 6 + 3x + -2x2 = -1x + x Combine like terms: -1x + x = 0 6 + 3x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -3 + -1.5x + x2 = 0 Move the constant term to the right: Add '3' to each side of the equation. -3 + -1.5x + 3 + x2 = 0 + 3 Reorder the terms: -3 + 3 + -1.5x + x2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -1.5x + x2 = 0 + 3 -1.5x + x2 = 0 + 3 Combine like terms: 0 + 3 = 3 -1.5x + x2 = 3 The x term is -1.5x. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x + 0.5625 + x2 = 3 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = 3 + 0.5625 Combine like terms: 3 + 0.5625 = 3.5625 0.5625 + -1.5x + x2 = 3.5625 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = 3.5625 Calculate the square root of the right side: 1.887458609 Break this problem into two subproblems by setting (x + -0.75) equal to 1.887458609 and -1.887458609.Subproblem 1
x + -0.75 = 1.887458609 Simplifying x + -0.75 = 1.887458609 Reorder the terms: -0.75 + x = 1.887458609 Solving -0.75 + x = 1.887458609 Solving for variable 'x'.
